JWL relocated a plut in his book Flathead facts. I thought tht was such a good idea I did tne same. Unfortunately I haven't had an opertunity to try it out. The location is in the center of the transfer area. I too agree the piston takes it's self out of the equasion when the piston to head clearance is very tight. This forces all the AF in the cylinder into the transferarea and with a power tip plug aids in firing a very lean mixture. Thus increasing economp in cruise. The trick here is to have an ignition and fuel system that can comtrol the spark curve and AF at the same time. I think Richard came close to this. The only change I'd make to this is to install the plug at the same angle as the transfer area. Here again the angle is important as it's partof the intake port after the AF leaves the valve. And yes Recardo is one of my heros. I've read all his publications. What's important is to keep testing
